This song is just completely about debauchery on more extreme levels (sex, drugs, alchohol), but he relates it all to very innocent-enough things like jellybeans and chocolate milk to illicit a much stronger feeling of empathy and understanding.
In doing all these things he's making his life inbalanced and maybe ruining chances he's had with people. He's only asking that you forgive his slightly greedy tendencies as human nature.
